Джюдза

Juza of the Clouds (雲のジュウザ, Kumo no Jūza) is the childhood rival of Raoh and a martial art prodigy who uses a self-styled martial art (我流の拳, Garyū no Ken) that suits his free-spirited personality. A childhood friend of Yuria, Juza fell in love with her as they grew up, but his hope of pursuing a relationship with her was shattered when he learned that they were half-siblings from the same father. Afterwards, Juza began living a care-free life of promiscuity, indifferent to the cause of the other Goshasei until he learns the true identity of the Last Nanto General.

Juza challenges Raoh to a fight and manages to stall him for a while by stealing his steed, Kokuoh-Go, but is eventually defeated in one of Raoh's most grueling battles. (Source: Wikipedia)
